lifeSurface
This module reads out a 2D surface of the game of life module The outcome is a scaled based upon how many coordinates are within the surface. Each step has 4 possible values, 0,1,2,3, and all steps are added together, scaled to the total amount of steps*3 (*3 because each step has 3 as its highest value). Using the min/max parameters, you can set the minimum and maximum output values.
